Adjustable output, but lower current Isolated 22-290vdc to 3.6-15vdc buck converter I hadn't seen these before, they could be quite useful. I might get a handful for a rainy day. I have been a bit doubtful of the usual 240v plugpack type boards because some of them don't start reliably at lower voltages  ...  and I'm running 48v, so it can be close. I did just use one on the new control board for the Warpverter  ...  but I checked it over and over again to make sure it would always start from about 46v and upwards. That is what I also use in my PV Combiner Monitor board (Solar array is 21 panels with VOC of 109 volts) for my latest 6KVA solar project. Running for two months now, so far no problem yet.
